Location with Plenty of Sun:

Tomatoes need plenty of sun, at least eight hours a day to be productive and to keep the soil and roots warm. Organic tomato gardening is based on the ideal garden location. Tomatoes thrive as much on heat as they do the sunlight. If you have to increase the level of light or heat, then sometimes a reflective back fence can help. It can be as simple as a white sheet staked between two fence poles to reflect more light onto the tomato plants.

Temperatures:

Plants do the best when the soil temperature is over 55 degrees and the night-time temperatures don't get colder than that. On the other hand, tomatoes have a hard time withstanding a heat wave for very many days when it reaches over 90 degrees. If the temperatures at night are cooler than 55 degrees, you may need to cover your plants with buckets or sheets overnight. If it is getting extremely hot during the day, you need to provide shade, by hanging a sheet on one side of the garden to block the hottest sun of the day.

Staking and Pest Control:

In organic tomato gardening, staking plants by keeping them off the ground protects them from soil that is laden with harmful plant insects. Natural pest control in organic tomato gardening also means that you don't re-plant tomato plants in the same place you may have experienced diseases or pests the year before. Organic tomatoes are to be grown in an area that has not been chemically treated in three growing seasons, so you may have to relocate plants.

Watering:

Uneven watering can be responsible for sporadic growth of fruit and can also cause problems with rot diseases. Two good waterings per week, with the ground soaked six to eight inches is usually sufficient for tomatoes. Of course, they love water, so if it gets extremely hot, you will have to water more often for them to stay productive.

Mulch for Weed Control and Preserving Moisture:

By using black plastic around your plants, you will discourage weed growth and keep warmth in the soil. This can help direct water to the plant's root system when sloping towards the plant. You can keep weed growth down and moisture in by laying heavy layers of newspaper around the plants and keeping them damp.

Pruning:

By pruning the suckers at the joints of the stem and leaves, you will focus more of the plant's energy on bearing fruit. If you don't prune, you will get more tomatoes, they will be smaller in size, and be sure you have plenty of mulch to keep the vines and fruit from direct contact with the soil. If you decide not to stake plants, the suckers will root themselves into the ground. This can help provide more water. If they are not rooted, they will take more of the water the plant gets.

Fertilizer:

You can use natural fertilizers, such as manure or fish emulsion on the tomato plants. Using compost from your recycling pile is another way to add nutrients without chemicals, when you are organic tomato gardening.
